IM PROVEM ENT IN INHALERS.

Specification forming part of Letters Patent No. l 99,140', dated January 15, 1878; application filed December 8,1877.

To all whom tmag/ concern:

Be it known that I, OLIVER P. BARBER, of

Saginaw, in the county of Saginaw and State of Michigan, have invented certain Improvements in Inhalers, of which the following is a specification My invention relates to that class of inhalers in which acid and alkali vapors are combined and passed through a Wash-chamber to remove the impurities, Sto.; and the improvements consist in constructing the chambers to t directly against each other, and uniting them by a detachable coupling; in providing the chambers with outlet-mouths at one side, and a communicating tube on the other, in order that the contents of either chamber may be emptied out without causing the passage from one chamber to the other, or the escape from the otlfer; in suspending the acid chamber or tube within the top of the alkali-chamber in such manner that the chamber may be inverted without danger of the acid passing into the alkali-chamber.

Figure l represents a perspective view of my apparatus; Fig. 2, a longitudinal vertical section of the same Fig. 3, a view illustrating the device in an inverted position, showing the action of the parts.

A and B represent two glass vessels or chambers, preferably alike in form and size, each made in one piece, with a neck at the upper end, to admit of its being readily filled and emptied. The two vessels have their sides flattened or otherwise shaped, in order that they may be tted snugly and closely against each other, side by side, as shown. Around the outside of the two chambers or bottles I place a band, C, by which they are held firmly and solidly together, but which may be readily removed with the lingers to admit of the chambers being separated when they are to be cleansed, or when for other reasons it may be desired to separate them.

In order to prevent the sliding or shifting of the two chambers in relation to each other, their adjacent faces will be provided with vertical and transverse ribs, or other suitable interlocking elevations and depressions.

In order to facilitatethe application and adjustment of the band, the vessels or bottles will be provided with external ribs or lips, to serve as stops for the band to rest upon.

In order that there may be no doubt or mis- 'take in charging the vessels, one has the word Acid77 and the other the word Water 7 ca-st thereon, and on each a mark is also cast, to indicate the height which the fluid is to have therein. While it is preferred to make the vessels of a semicircular or approximate form in cross-scction,and to apply the band around them, as shown, it is manifest that they may be varied in form, and the application of the fastening modified. Thevessel or chamber A, whichis to contain the acid, has suspended through a cork in its neck an alkali tube or chamber, D, open at both ends, but with its lower end contracted in size, as shown. The tube or chamber is suspended, it will be seen, freely and independently within the ch amber or bottle A, in such manner that when the vessel is inverted for the purpose of discharging the water-the acid will iiow down around the outside of the tube D, in the manner shown in Fig. 3, the end of the tube remaining constantly above the level of the acid, in such manner thatthe latter is retained closely within the vessel and prevented from entering the alkali-tube. The alkali-tube will be provided with a filling of sponge or other absorbent material. YThe two vesselsA and B are connected by a tube,E,eXtending at its ends through holes in their tops, which holes are bushed or lined with cork, rubber, or other packing, to insure-a tight joint.

The tube E extends, as shown, below the level of the iiuid in vesselB, but not below that of the acid. Into the top of vessel B, I insert an inhaling-tube, F, as shown.

. The instrument or apparatus is charged by introducing aproper amount of acid into chamber A, pure water into chamber B, and saturating the lling-in chamber D with the al kali.

Upon applying suction to the tube F atmospheric air is caused to pass through the alkali in chamber E, and thence over the surface of the acid in chamber A, and then through the tube l) into chamber B, Where it is compelled to pass through the water, by which it is thoroughly washed and cleansed, and the excess of acid or .alkali and any existing foreignmatters or impurities removed. The resultant vapor, pure, cool, and pleasant to the taste, is sues through the tube F.

rIhe necks a and b, it will be noticed, are located at or near one side of the bottles or ohambers,and the communicating tube E near the opposite side. This arrangement admits of the two vessels being inverted to pour off the contents of either one Without danger of the fluid in one vessel passing through the tube into the other.

I am aware that it is old to retain alkali in a sponge in a tube of an inhaler, and I lay no claim thereto.

-lIaving thus described my invention, what I claim is- 1. yIn an inhaler, the combination oi' two glass vessels, A B, constructed to iit solidly together, and a removable band encircling and uniting said vessels, as shown.

' 2. An inhaler-body consisting of the two vessels or bottles provided with interlocking surfaces, and secured together by means of the encircling band, substantially as shown.

3. In an inhaler, the alkali-chan1ber suspended freely Within the acid-chamber, and provided with a filling of absorbent material to retain the alkali, as shown, whereby the iuversion of the inhaler is permitted Without causing the escape or admixture of the acid and alkali.

4. The vessels A B, having the necks or mouths located at or near one side, and the communicating tube located at or near the other side, substantially as and for the purpose set forth.
